Benefits Of Using Liposome In Administering Drugs

By Rena Hudson


A liposome can be defined as a tiny vesicle, made from the same substance as the cell membrane. In the medical field, it is filled with drugs and is therefore adopted in the delivery of drugs for the treatment of cancer. The use of this technology has increasingly become popular due its benefits. Below are some of the advantages medical researchers say liposomal method of drug delivery can provide.

One of the things that medical researchers have been working on for many years is how to accelerate the effectiveness of drugs administered. The traditional methods that have been adopted in the past make it difficult for the treatments administered to reach their target and create the required healing. This is what the new technology that involves the creation of lipid structures solves and leading pharmaceutical companies are already buying the idea.

Naturally charged liposomes have the rare capability of penetrating into the biofilm and mucus. This therefore leads to enhanced drug concentration for the killing of bacteria. Substances found in the mucus or biofilms of a patient are normally produced by bacteria for their protection. The use of the new technology ensures that these materials are penetrated with antibiotic drugs to result into healing. This can only be possible with the breaking of the barrier.

The use of traditional systems of administering drugs is known for causing increased toxicity to the body, which leads to adverse effects. However, this is not the same thing with liposomal technology as it ensures that treatment is only delivered to the relevant areas. Fewer concentrations of drugs are used and only released to the affected areas as opposed to the large quantities used in traditional methods.

Bacteria that cause diseases do create layers of mucus and biofilms to protect themselves from the treatments administered. This plays a key role in hampering the efforts to deal with the microorganisms and treat the disease caused. However, with the coming of the new technology, the lipid structures adopted have the capability of breaking into the barriers to deliver the drugs. The innovation has been much welcome by many pharmaceutical firms in the industry.

It is also believed that with the ability of the structures to only release their contents near the places affected by disease, chances of adverse reactions are reduced. The lipid components as adopted in this method are similar to the ones existing in the lungs and ensure a more natural metabolism. This is not the case with other delivery systems that are produced from man-made materials.

Liposomes have also been widely adopted in the cosmetics industry. This is because of their proven ability to deliver moisture to the skin. The lipid that make the delivery system contain moisture and when the bubble breaks the skin is hydrated. This makes the method an excellent ingredient in the manufacturing of dry skin products.

Liposome does more than simply moisten the skin. They also create useful barriers on the surface of the skin hence offering protection against agents that can cause diseases including rashes. The layer also offers extra protection against other external aggressors like sun.
